7.2.3 Protected Expansion I/O Board : Output Circuit
The following diagrams illustrate cases where #48 through #79 (for the first Expansion
I/O Board) are assigned to the Protected Expansion I/O Board’s inputs and outputs. The
I/O number assignment depends on the controller software settings.
CAUTION
■
Use the PNP-type of wiring diagram for CE conformance. Be sure to wire
